OVEN-WALL CONSTRUCTION.

Application tiled July 1.6, 1923. Serial-No. 651,997.

to provide a wall or partition which is light in weight but which will,nevertheless, be eflicient in the matter of insulating against heat andcold the spaces enclosed or separated thereby.v A further object of theinvention is to provide a wall or panel construction which is durableand in which the exterior surface may be of metal, withl interposedbraces or'stanchions to which the exterior wall sections may beconveniently secured and without the necessity -for employing am'etal-to-metal contact between such external surfaces. My invention isparticularly adapted lfor Athe construction of ovens, such as core,enameling and heattreating ovens. A

I accomplish` the foregoing object and more limited objects which willappear hereinafter, in and through the construction and arrangement ofparts shown in .the drawings, wherein Fig. l represents,V a

horizontal sectional view through the corner of a room or buildinghaving my invention applied thereto; Fig. 2 a vertical section on theline 2-2 of Fig. l; and Fig. 3 a detail in horizontal section showingthe manner in which contiguous panels may be conveniently united.

Describing by reference characters the various parts illustrated herein1 denotes the outer and 2 the inner sheet metal covering* for the Wall.Each of these covers has adjacent thereto a sheathing 3 ofheat-insulating material, such as magnesium board or the like, moldedinto suitable sheets. My invention m'ay be conveniently embodied inpanels, each panel havwall sections 1. 3 and 2, 3 thereof, an upperspacing and frame member 4,4 a lower spacing and frame vmember 5, andvertical spacing and frame members 6. In addition to the upper and"lower members 4 and 5,' each panel may have one Or more intermedlatehorizontal memor panel by tions fthe -walls or panels.

bers 7 and one or more vertical members 8, according to the dimensionsof the panel and the frequency of the bracing required between theopposed sides of the wall or panel.

For the members 4, 5, 6, 7 .and 8, I employ insulating material to whichthe Opposite sides of the panel may be secured bymeans of nails. Forsuch members I prefer to use resilient asbestos board, made by mixingthe ingredients thereof and compacting the. mixture into stanchion shapeBy using such material for the spacing and^ frame members, I am enabledto iorm a wall securing the opposed wall sec- 1, 3 `and 2; 3 to suchmembers by such cheap and' ordinary fastening means as nails lor screws.As walls or panels of this general character have been constructedheretofore, angle irons have been used for the purpose of spacing apartwith a press.

and bracing the opposed sides or sections of not only because of theWeight, but because of. the expense incurred in securing the oppositesides of the alls to such angle iron members.'

In'Fig. 1, a corner of an oven or heattreating construction is shown. Inmaking such corner, a special shape is given to the ends\of the adjacentwall sections Orpanels. It will be noted that the metal sheet 1 and thelining or the sheet 2a and lining or sheathing 3". The same is true asto the length of the sheet 1 and lining or sheathing 3 as compared withthe length of the opposed sheet` 2 and lining or` sheathing 3. Thisenables the ends to be readily assembled into a corner, using verticalstanchions Gand 6a as a. comlposlte corner jolst. l

For the ordinary panels, other than corner panels, the two oppositesides 1, 3 and 2, 3 will be of the same lenth-see Fig. 3, and the metalcovers 1 -and 2 and thesheathings 3 will be extended beyond theiradjacent vertical frame members 6, and,v if.

necessary, in like manner beyond the uppermost and lowermost horizontalframe members '6. .The metal covering, however, will lbe extended stillfurther, in order that a rolled or curled joint may be` formed be-rtween' adjacent panels, as indicated at 9.

A wall for the purposes specified may,l of course, bey built complete,in the saine manner as a single panel; or it may be,

This is objectionable,

sheathing '3EL are longer thanv builtl up from a number of panels,assembled in the manner indicated in Fig. 3 land With the corners formedas shown in Fig. 1.

A wall or panel constructed in accordance with my invention has theadvantage that it is comparatively vcheap of production, is

light in weight thus minimizing the cost of transportation may bereadily asseml bled on the job, and affords an effective heat insulationbetween the inner and outer surfaces of the wall. -The use of theparticular kind of material for stanchions or spacing and framingmembers enables me to use cheap screws or nails for fastening thecomposite sides to the said braces or stanchior-s;

. and I am enabled toobtain all the necessary rigidity and insulationwithout the use of metal angles for the braces or stanchions. The air sace between the stanchions and the sides o the partition or wall may befilled with any suitable insulating or nonconducting material, such asmagnesium board, air-cell board, etc.

yHaving thus described my invention, what I claim is: f

1. A wall construction comprising ali intermediate frame work ofresilient asbestos board having applied to opposite sides thereof 'wall'sections each having an external -sheet metal covering and an internallayer or sheathing of insulating material, the said wall sections beingsecured to thesaid frame,

formed of resilient asbestos board, and oplposed wall sectionssecured tosaid stanchions, each section comprising `an outer e sheet metalcovering and an inner layerof -rality of horizontall insulatingmaterial,and screws or nails fastening the said wall sections to thesaid stanchions.

4. A wall construction comprising a pluand a plurality o verticallyarranged stanchions constituting an intermediate intermediate arrangedstanchions frame work, the said stanchions being formedpof insulatingmaterial capable of receiving and sustaining a screw, and opposed wallsections secured to said stanchions, each4 section comprising an outerlsheet metal covering and an inner layer of insulating material, andscrews or nails astening the said wall sections tothe said stanchions.

5. A wall section or panel comprising upper, lower and side membersorstancliions of'resilient asbestos board, and opposed wall sectionssecured tothe said stanchions, each wall section comprising an externalsheet metal covering andan inner insulating sheathing, the ends of thesheet metal coverings and of their cooperating sheathings projectingthereto and the ends of the coverings pro- `ecting beyond theirrespective sheathings, whereby the projecting metal endsoi1 one' beyondthe stanchions adjacent,

such panel may be secured to the projecting metal ends of an adjacentpanel.

' 6. A wall section or panel comprising upper and lower and side membersor stanchions of insulating material, a wall section secured to thejsaidstancliions, said section comprising an external sheet metal coveringand an in'ner insulating sheathing, the ends` of the sheet metalcovering projecting beyondlthe ends of the sheathing, whereby theprojecting metal ends ofone such panel may be secured to the projectingmetal ends of an adjacent panel. Y

7. A wall section or panel comprising a marginal "frame work ofresilient insulatf ing material, and a pair of yWall sections secured tosuch frame work andy comprising an outer sheet metal covering and aninner insulating sheathing,'the ends of the sheet metal coveringsprojecting beyond the ends of the sheathing and ybeyond the framemembers adjacent thereto, of the sheathing of one panel are adapted toabutagainst the ends of the sheathing-of the adjacent panel and thesheet metal ends of said panels may be united vby a doublerolled bead.

8. A wall section or panel comprisingI a sheathing.

In testimony whereof, I hereunto aiiix 110 m si ature.
